What reading level is Diamond Drilling for Gold And Other Minerals a Practical Handbook On the Use of book?
To quickly assess the difficulty of the text, read a short excerpt:
"For example, let HT = 150 yards, HM = 112 yards, and MT =100 yards, measured hori- zontally.
Let the angle M H T = 41 48' 37", and let T be the deepest borehole, and the floor of the seam in the borehole M be 32 yards, and in the borehole H 73 yards, higher than in the borehole T. It is required to determine the strike and dip of the seam, when T H courses 172 30'. " From the first equation given, = 199-41 yards.
"Now, T + N = 180 41 48' 37" = 138 IT 23", and half T + N = 69 5' 41 -5". From th...e second equation H 98 DIAMOND DRILLING.
" From this, half T N is found by logarithms to bo 20 18' 55". Half T + N being 69 5' 41-5", T is equal to 89 24' 36-5", and N is equal to 48 46' 46-5".
" As the strike of T H is 172 30', and as T N lies to the right of T H, the strike of the latter is (172 30' + 89 24' 36-5") 180 = 81 54' 36-5".
; ' The angle of dip H o p is found from the equation _ _ 73 " 150 sin 89 24' 36-5" By aid of logarithms, the angle H o P is found to be 25 57' 7". " The strike of the reef is therefore 81 54' 36-5", and its dip 25 57' 7".
